plot_graph - general plot of a graph

### Calling Sequence

  `plot_graph(g,[rep,rep1])`

### Parameters

- `g`: graph list
- `rep`: row vector of 13 values for the parameters of the plot
- `rep1`: row vector of 4 values defining the plotting rectangle

### Description

`plot_graph` plots graph `g` in a Scilab graphical window. The optional arguments `rep` and `rep1` define the parameters of the plot. If there are not given, a dialog box for the definition of these parameters is opened.

`rep` must be a row vector with 13 integer numbers which must be 1 or 2. The meaning of the values of `rep` are:

Frame definition: 1 = Automatic 2 = Given (see below)

Plotting arrows: 1 = yes, 2 = no

Plotting sink and source nodes: 1 = yes, 2 = no

Plotting node names: 1 = yes, 2 = no

Plotting node labels: 1 = yes, 2 = no

Plotting arc names : 1 = yes, 2 = no

Plotting arc labels: 1 = yes, 2 = no

Plotting node demand: 1 = yes, 2 = no

Plotting edge length: 1 = yes, 2 = no

Plotting edge cost: 1 = yes, 2 = no

Plotting edge min cap: 1 = yes, 2 = no

Plotting edge max cap: 1 = yes, 2 = no

Plotting edge weight: 1 = yes, 2 = no

If `rep(1)` is 2, the frame definition must be given by `rep1`. Otherwise, `rep1`can be omitted. `rep1` must be a row vector `[orx,ory,w,h]` giving respectively the coordinates of the upper-left point, the width and the height of the plotting rectangle.

### Examples

    // simple graph with different choices for the plot
    ta=[2 2 1 1 2 4 3 3 4];
    he=[2 2 3 2 3 2 1 2 1];
    g=make_graph('foo',1,4,ta,he);
    g('node_type')=[1 1 1 2];g('node_name')=string([1:4]);
    g('node_x')=[73 737 381 391]; g('node_y')=[283 337 458 142];
    g('node_color')=[3 3 3 11];
    g('node_diam')=[30 30 30 60];
    g('edge_color')=[10 0 2 6 11 11 0 0 11];
    rep=[2 2 1 1 2 2 2 2 2 2 2 2 2];
    rep1=[100 -400 650 300];
    xbasc(); plot_graph(g,rep,rep1);
    rep=[2 1 1 1 2 2 2 2 2 2 2 2 2];
    x_message('plot the graph with different parameters');
    xbasc(); plot_graph(g,rep,rep1);
    // plotting using dialogs
    xbasc(); plot_graph(g);
    xset("thickness",4);
    xbasc();
    plot_graph(g);
